White supremacist David "Joey" Pedersen wore an expression of indifference Monday as his sister sat down a few feet from him in a Portland courtroom to address him.

But as Holly Perez began to unleash her anger on her younger brother, the 34-year-old admitted killer fidgeted. He drank a sip of water, looked up at the ceiling and shifted in his seat as she condemned his justifications for murdering their father, stepmother and two strangers who had given him and his then-girlfriend a ride.

"How do you live with yourself each day knowing your senseless deeds have caused a mother to bury her child?" she asked. "How do you sleep at night with the blood of your victims on your hands? ... You're nothing but a coward with a skewed ideology of the human race."

Her words came shortly before Senior U.S. District Judge Ancer Haggerty handed down the sentence recommended as part of a plea agreement – two life terms without the possibility of release for the carjacking murders of Cody Faye Myers, 19, and Reginald Alan Clark, 53. The terms are to be served concurrently with the two life sentences he has received under Washington state prosecution for the murders of his father, David "Red" Pedersen, and stepmother, Leslie "DeeDee" Pedersen.

Monday's sentencing was the final hurdle in resolving criminal charges against those involved or associated with a three-state, 10-day killing spree in 2011 as part of Pedersen's and Holly Ann Grigsby's white supremacist "revolution." The couple killed, stole cars and used their victims' credit cards to finance their plan to target Jewish organizations.

As authorities pursued them from Washington to Oregon, where they killed Myers, they shifted their focus south to Sacramento to carry out their revolution.

But shortly after killing Clark, their last victim, the couple was stopped and arrested by a California police officer who recognized their car from a suspect bulletin. Co-defendant Grigsby was sentenced to life in prison last month. Accomplices Corey Wyatt and Kimberly Scott Wyatt were also sentenced last month.

At his sentencing, Pedersen offered his own tirade.

"I can only laugh sardonically that I sit here, being sentenced for crimes for which the United States government has accused me," he said, criticizing government support of Israel, its use of drones and civilian deaths in Iraq by the U.S. military.

But he also took aim at those prosecuting his case, which was at risk of unraveling because of serious allegations of misconduct by Oregon State Police Det. Dave Steele and accusations of ethical failures by the prosecutors. Witnesses had testified in April that Steele failed to turn over evidence, backdated and shredded evidence records, collected private legal phone calls between Pedersen and his defense team and lied when challenged about his handling of the case. In addition, Pedersen's attorneys argued that prosecutors failed to meet ethical standards by not immediately notifying them that investigators had confidential legal calls.

Haggerty was weighing whether to find the prosecution team had acted in bad faith or violated Pedersen's 6th Amendment right to counsel.

Pedersen accused them of allowing their zeal to convict him overrun their responsibility to uphold the law.

"I feel the malfeasance at the (U.S. Attorney's Office) is nothing short of remarkable," he said.

Pedersen ultimately dropped the challenge as part of his plea agreement, which also included a deal with prosecutors that significantly cut the prison sentence for Wyatt and ensured Kimberly Scott Wyatt would receive only probation for their roles assisting Pedersen and Grigsby.

In his remarks, Pedersen defended his actions, saying he regretted he did not make more progress in his white supremacist revolution.

"I offer no excuses because none are needed," he said, adding that he could not sit by while "western identity is being destroyed" by other cultures.

Pedersen and Grigbsy have said in the past that Pedersen killed his father because he believed him to be a child molester and killed his stepmother for defending him. They killed Myers for his car and to get rid of a potential witness, and they killed Clark both for his car and because they viewed him as a "Negro degenerate."

Later, as he continued to criticize the U.S. Attorney's Office as self-righteous and sanctimonious, his sister yelled out, "Shut up." He paused and briefly resumed but soon ended his comments by turning to family and friends of Cody Myers. "I wish you whatever peace you may find," he said.
